It looks like you are up against the usual virtue-signallers who refuse to see that there could be several complex and nuanced reasons for why the war occurred. It’s more important to show off about how they are against slavery - as if that’s taking some revolutionary bad-ass position, lol!
Lol. My dear, lol, I have no doubt that you are aware that your friend, “lampy” is the most virulent Lincoln basher, hater on FreeRepublic? Lol
Virtue signaling is definitely a part of it, but I think for many of them another part is defending the actions of their ancestors as "good people."
Neither side wants to believe they have "corruption of blood" as the English used to put it, and both sides want to revere their ancestors, even though they were fighting against each other.
I think the real tragedy was the creation of those conditions where family had to fight against family. That is so unnatural it would seem to be an obvious evil.
But yes, for many modern day virtue signalers, it's important for them to let people know how much they really really hated slavery.
It's the zeitgeist of modern USA.
